AUTOMATIC APPARATUS FOR CARBURETING AIR AND OTHER GASES.

Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed March 29, 1905. Serial No. 252,733.

To (all whom it may concern:

Be it known that I, EDOUARD BOUCI-IAUD- PRAoEr of No. 33 Avenue dEylau, Paris, France, have invented a new and useful Improvement in Automatic Apparatus for Carbureting Air and other Gases, which invention is fully set forth in the following specification.

This invention relates to an apparatus serving to effect in an automatic manner either the carburization of air or of any gas, with a view 'to render it combustible, and consequently. suitable for furnishing light, heat, or motive power, or for the enrichment of gases already combustible, but of an insufiicient calorific or luminant powersuch as water-gas, gas from wood, and generally all poor gasesor for effecting the attenuation of gas having excess of carburization, such as acetylene. All carbureting liquidssuch as benzenes, alcohols, ethers, all essences of petroleum, of tar, &c.can be employed even if mixed. The carbureting liquids are contained in one or several reservoirs situated in a raised position relatively to the rest of the apparatus, and the liquid is extracted automatically always in a manner propor tional to the quantity of air or gas to be carbureted, enriched, or attenuated by means of the arrangement which will be described relatively to the drawings annexed to the present description.

Figure 1 is a front view; Fig. 2, a side view; Fig. 3, a plan. Figs. 4, 5, and 6 are respectively a vertical section, a horizontal section, and a side view of the actual closing appara;

. tus.

The apparatus consists of two reservoirs,

a 0, containing the carbureting liquid and which can be put alternately into action, so as not to interrupt the supply during the filling of one thereof. Each of these reservoirs is provided with a level-indicator tube 11, showing by a suitable scale the..contents of this reservoir. A cock 0 at the bottom of each reservoir is connected, by means of a flexible mouth constituting a dischargefor the carbursting liquid, and they communicate, respectively, with the tubes d. The third tube g serves for collecting the liquid which passes into the gage-tube e and to conduct the same through a flexible tube 72, into a gas-meter of suitable size, (shown at i on the drawings.) The liquid spreads in a thin layer upon the water contained in the meter and evaporates instantaneously in contact with the gaseous current passing through the apparatus.

The vessel 6 is mounted in a sleeve 76, carried by a screw-nut m, formed in two parts, articulated by means of a spring-hinge n and embracing a screw-spindle 0, arranged vertically in front of the apparatus. This screw is situated on an axis connected to the drum or the clockwork of the meter, so as to revolve at a speed always proportional to the discharge of the metersuch as, for example, one revolution per cubic meter of air passing through the apparatus.

The pitch of thescrew is determined by the other conditions of the construction of I the apparatus in such manner as to realize a constant degree of carburization whatever may be the quantity of gas that the apparatus has to supply. p

The action is as follows: The air or gas under pressure enters the meter through the pipe p, for example, and causes the meter to revolve. It then issues carbureted through the second pipe 9. The motion of the meter determines the proportionate rotation of the screw 0, which in revolving causes the screwnut m, and consequently the discharge-tubes f, to descend progressively, one of the tubes at least being in communication with the corresponding reservoir. By virtue of the principle of communicating vessels the level of the liquid is the same in the reservoir and in the tube f. When the screw-nut descends, owing to the rotation of the screw, the liquid overflows the tube f and falls into the vessel a, When it has risen to the level of the upper opening of the tube g, it flows off through the same into the meter and there carburates the air or the gas passing through the latter.

When the screw-nut has arrived at the bottom of its course, it is brought baclito its should be forgotten to raise the latter when,

reduced to a smaller diameter below the latter, so as to present a smooth part which would be embraced by the screw-nut m if it it has completed its descending motion in order thus to avoid jamming and damage to the apparatus.

It will be seen that. the discharge of carbureting liquid will depend on the speed of rotation of the screw 0 and upon the pitch of the latter. It is therefore easy to obtain at will different degrees of carburization by replacing the screw 0 by another one of a suitable difi erent pitch, so as to cause the dis charging-tubes through which the liquid flows into the meter to descend at a greater orsmaller speed.

Having thus described. the nature of my said invention and the best means I know of carrying the same into practical effect, I a-i 1, In apparatus for carbureting air or other gases, a carbureting-chamber, a reservoir for the carbureting liquid, a movable receptaclecommunicating with said reservoir and said carbureting-chamber, and motor means acting to vary the elevation of said receptacle relative to the height of the liquid in the reservoir, thereby effecting passage of liquid from the reservoirinto the receptacle and from the latter into the carburetingehamber in regulated quantity.

2-. In apparatus for carbureting air. or other gases, a carbureting-chamber, a reservoir for the carbureting liquid a movable receptacle, flexible pipings connecting said movable. receptacle to said reservoir and said carbureting-chamber, and motor means-for imparting relative movement between the receptacle and reservoir thereby effecting passage ofliquid from the reservoir into the receptacle and from the latter into the car,- bureting-chamber in regulated quantity. 1

3. In apparatus for carbureting air or other gases, a carbureting-chamber, a reservoir for the carbureting liquid, a movable receptacle, flexible piping through which said receptacle communicates with the reservoir and the carbureting-chamber, and motor means acting to vary the elevation of said receptacle relativeto the height of the. liquid in the reservoir, thereby effecting passage of liquid from the reservoir into the receptacle and from the latter into the carburetingchamber in regulated quantity.

4. In apparatus for carbureting air or other gases, a meter through which the air or gas to be carbureted is made to pass, a reservoir for the. carbureting liquid, a screw-spin dle receiving rotary motion from the mechanism of the motor, a screw-nut on said screw-spindle, a vessel fixed to said nut, a tube emptying into said vessel from said res- 5.

6. In apparatus for carbureting air and other gases, a wet gas-meter through which the air or gas to be carbureted is made to pass, one or more reservoirs of carbureted liquid raised above the said gas-meter, a vertical screw-spindle receiving rotary motion from the mechanism of the gasmeter, a screw-nut on said screw-spindle, a vessel fixed to said nut, one or more tubes projecting up a certain height through the bottom of'the vessel, flexible tubes connecting the saidtube to the said reservoirs so that the liquid can flow from the latter into the former, cocks on said tube for cutting off communication between the vessel and reservoirs and a flexible tube connecting the lower part of the vessel with the inlet of the gasmeter so that the liquid'can flow from the former intothe latter, substantially as described.

7.
